Edited at 2020-09-27 06:06:30Halloween has many faces. The theme you envision should influence how you decorate the party space. Jack-o'-lanterns and friendly ghosts are more lighthearted Halloween characters. Zombies, witches, and vampires are much darker. If you want to celebrate all the fun sides of Halloween, then it’s okay to mesh the cute with the frightening. Here is a mind map which lists down the 39 Cutest Couples Halloween Costumes of 2021.
Halloween simply wouldn't be Halloween without the movies that go along with it. There's nothing like a movie night filled with all the greatest chainsaw-wielding, spell-binding, hair-raising flicks to get you in the spooky season spirit. So, break out the stash of extra candy, turn off all the lights, lock every last door, and settle in for the best of the best Halloween movies. Here are the 35 Halloween movies listed on the mind map based on the year of release.
This mind map contains lots of interesting Halloween trivia, great tips for costumes and parties (including food, music, and drinks) and much more. It talks about the perfect Halloween night. Each step has been broken down into smaller steps to understand and plan better. Anybody can understand this Halloween mind map just by looking at it.

sitemap.xml
is it complete?
check syntax
General recommendations
XML file named "Sitemap.xml"
file must be no larger than 50MB when uncompressed
place sitemap in root folder - The location of a Sitemap file determines the set of URLs that can be included in that Sitemap. A Sitemap file located at http://example.com/catalog/sitemap.xml can include any URLs starting with http://example.com/catalog/ but can not include URLs starting with http://example.com/images/.
no more than 50,000 URLs for a single sitemap
If you have more than one Sitemap, you can list them in a Sitemapindex.xml file and then submit the Sitemap index file to Google. You don't need to submit each Sitemap file individually.
If your site is accessible on both the www and non-www versions of your domain, you don’t need to submit a separate Sitemap for each version. However, we recommend picking either the www or the non-www version, and using recommended canonicalization methods to tell Google which version you are using.
Do not include session IDs in URLs
syntax
<?xml version=”1.0” encoding=’UTF-8’?><urlset xmlns=’http://www.sitemaps.org/schemas/sitemap/0.9’><url><loc>http://www.mysite.com/</loc><lastmod>2012-05-25</lastmod><changefreq>monthly</changefreq><priority>0.8</priority></url><url>etc, etc, etc</url></urlset>
<Tag> - <Importance> - <Description><urlset> - Required - Encloses all information about the set of URLs included in the Sitemap.
<url> - Required - Encloses all information about a specific URL.
<loc> - Required - Specifies the URL. For images and video, specifies the landing page (aka play page, referrer page). Must be a unique URL.
<lastmod> - Optional - The date the URL was last modifed, in YYYY-MM-DDThh:mmTZD format (time value is optional).
<changefreq> - Optional - Provides a hint about how frequently the page is likely to change. Valid values are:- always. Use for pages that change every time they are accessed.- hourly- daily- weekly- monthly- yearly- never. Use this value for archived URLs.
<priority> - Optional - Describes the priority of a URL relative to all the other URLs on the site. This priority can range from 1.0 (extremely important) to 0.1 (not important at all).Does not affect your site's ranking in Google search results. Because this value is relative to other pages on your site, assigning a high priority (or specifying the same priority for all URLs) will not help your site's search ranking. In addition, setting all pages to the same priority will have no effect.
Image Sitemap
<?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1"> <url> <loc>http://example.com/sample.html</loc> <image:image> <image:loc>http://example.com/image.jpg</image:loc> </image:image> <image:image> <image:loc>http://example.com/photo.jpg</image:loc> </image:image> </url> </urlset>

Moved page
301
The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs. Clients with link editing capabilities ought to automatically re-link references to the Request-URI to one or more of the new references returned by the server, where possible. This response is cacheable unless indicated otherwise.
Deleted page
404
404 Not Found: The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.
Temporary Redirect
302
302 Found (HTTP 1.1) / Moved Temporarily (HTTP 1.0) A 302 redirect is a temporary redirect. It passes 0% of link juice (ranking power) and, in most cases, should not be used. The Internet runs on a protocol called HyperText Transfer Protocol (HTTP) which dictates how URLs work. It has two major versions, 1.0 and 1.1. In the first version, 302 referred to the status code "Moved Temporarily." This was changed in version 1.1 to mean "Found."
307
307 Moved Temporarily (HTTP 1.1 Only) A 307 redirect is the HTTP 1.1 successor of the 302 redirect. While the major crawlers will treat it like a 302 in some cases, it is best to use a 301 for almost all cases. The exception to this is when content is really moved only temporarily (such as during maintenance) AND the server has already been identified by the search engines as 1.1 compatible. Since it's essentially impossible to determine whether or not the search engines have identified a page as compatible, it is generally best to use a 302 redirect for content that has been temporarily moved.
if the page you are removing has a suitable alternative page on your web site, then 301 it. Do not always 301 the page to your home page. If there is no suitable, and by suitable I mean, a page that is very similar to the page you are removing, then 404 the page.301 if there is a related and similar page to the page you are removing. 404 if there is not.
Redirect pages one-to-one, never many-to-one
Site URL
friendly url
keyword rich URLs
nevers use non-ASCII characters
www.example.com/page-title
page-title: keyword at beginning
blog:
www.example.com/2012/01/page-title
www.example.com/page-title (WordPress 2013)
URL Canonical
Good
http://www.mysite.com/
point to same domain
same subdomain
alfa.example.com can point to www.example.com
point https -> http
Bad
http://www.mysite.com
http://mysite.com/
http://www.mysite.com/index.html
http://mysite.com/index.html
chain canonical
syntax on id url
on page: http://www.example.com/page.html?sid=123
<head><link rel="canonical" href="http://www.example.com/page.html"/></head>

use sitemap.html
use homepage deep links for top products/pages
check most linked pages
Link
Links Position Weights
Links Higher Up in HTML Code Cast More Powerful Votes
External Links are More Influential than Internal Links
Links from Unique Domains Matter More than Links from Previously Linking Sites
Links from Sites Closer to a Trusted Seed Set Pass More Value
Links from "Inside" Unique Content Pass More Value than Those from Footers/Sidebar/Navigation
Keywords in HTML Text Pass More Value than those in Alt Attributes of Linked Images
Links from More Important, Popular, Trusted Sites Pass More Value (even from less important pages)
Links Contained Within NoScript Tags Pass Lower (and Possibly No) Value
A Burst of New Links May Enable a Document to Overcome "Stronger" Competition Temporarily (or in Perpetuity)
Pages that Link to WebSpam May Devalue the Other Links they Host
Internal Links
Internal Links Distribution
more internal links to important pages
use keyword in anchor text
use keywords in URL
use structured levels: draw a tree/SILO
better no more than 100 link on page
Warning: Internal nofollow

META Language Tag
<meta http-equiv="content-language" content="it">
Tip: better placed in sitemap
Multi Language:rel="alternate" hreflang="x"
in HEAD section
<link rel="alternate" hreflang="en" href="http://www.example.com/page.html" /><link rel="alternate" hreflang="en-gb" href="http://en-gb.example.com/page.html" /><link rel="alternate" hreflang="en-us" href="http://en-us.example.com/page.html" /><link rel="alternate" hreflang="de" href="http://de.example.com/seite.html" />
Meta Refresh (Warning, not safe)
Meta refreshes are a type of redirect executed on the page level rather than the server level. They are usually slower, and not a recommended SEO technique. They are most commonly associated with a five-second countdown with the text "If you are not redirected in five seconds, click here." Meta refreshes do pass some link juice, but are not recommended as an SEO tactic due to poor usability and the loss of link juice passed.
Force page refresh
Syntax
Place inside <head> to refresh page after 5 seconds:<meta http-equiv="refresh" content="5">
Redirect to http://example.com/ after 5 seconds:<meta http-equiv="refresh" content="5; url=http://example.com/">
Redirect to http://example.com/ immediately (BETTER):<meta http-equiv="refresh" content="0; url=http://example.com/">
An alternative is by sending an HTTP redirection header, such as HTTP 301 or 302
Robots meta tag
upload the robots.txt in the root directory
www.example.com/robots.txt
lang
<html lang="en">...</html>
In XHTML, the language is declared inside the <html> tag as follows:
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">...</html>
